xg exits cause of Unhandled Exception: System.ArgumentOutOfRangeException, Parameter name: startIndex

[Strubbl]

Sometimes my XG session gets killed because of an ArgumentOutOfRangeException. Is it possible to catch that one?

In case this exception occurs, XG does not exit in clean way so that the DB is saved.
